There is a pre-release package, which works fine with Python 3.4, here that you may install with:
pip install --pre -U https://github.com/HelioGuilherme66/robotframework-selenium2library/archive/v1.8.0b3.tar.gz
The Pull Request is waiting for merge.

As of now, Selenium2Library is not compatible with Python 3.5. Please use Python 2.7 instead.
